When the first networking equipment 31 fault, this first pair of bypass interface is for connecting first network 33 and the second networking equipment 32.
Below in conjunction with accompanying drawing, with specific embodiment, system provided by the invention is described in detail.
Embodiment 1:
In the embodiment of the present invention 1, propose a kind of group network system adopting active/standby mode to carry out dual-host backup, its structural representation as shown in Figure 4, wherein, first networking equipment as host apparatus, and is connected with first network, and the second networking equipment is as the alternate device of the first networking equipment.Concrete, first networking equipment and the second networking equipment can be the network equipments possessing various function, such as, it can be firewall box, also can be routing device, for routing device, as shown in Figure 4, first networking equipment is also connected with nucleus equipment respectively with the second networking equipment, for transmitting message mutual between nucleus equipment and first network.
First networking equipment arranges a pair bypass interface, for convenience of description, this is called first pair of bypass interface to bypass interface, they two interfaces comprised are called first interface and the second interface, wherein, first interface is connected with first network, and the second interface is connected with the second networking equipment.
Bypass interface possesses reliability properties, namely when its corresponding device breaks down, they two interface couplings comprised, thus make between these two interfaces, to form the path being similar to straight-through network cables, now, this equipment is equivalent to a netting twine for upstream and downstream equipment, thus this equipment that guarantee message flow can pass through fault continues to transmit between upstream and downstream equipment.
Due to the above-mentioned characteristic of bypass interface, in the group network system of the dual-host backup shown in above-mentioned Fig. 4, when the first networking equipment fault, namely first pair of bypass interface may be used for connecting first network and the second networking equipment, thus realize the transmission of message between first network and the second networking equipment, namely realize by the second networking equipment as alternate device, message mutual between transmission nucleus equipment and first network; And when the first networking equipment is normal, being communicated with between first network with the second networking equipment can be blocked, i.e. not mutual message between first network and the second networking equipment.
In order to reach the object of above-mentioned message transmissions, for routing device, can by the first interface in first pair of bypass interface of the first networking equipment and the second interface, and the IP address of the interface be connected with the second interface in the second networking equipment realization is set, be specifically as follows:
The IP address of the IP address and the second interface that arrange first interface belongs to different segment, and the IP address of the interface that the second networking equipment is connected with the second interface is set, phase same network segment is belonged to the IP address of first interface, preferably, the IP address that can arrange this interface of the second networking equipment is identical with the IP address of first interface, to ensure when the first networking equipment is normal, can not message transmission between first interface and the second interface; When the first networking equipment fault, first pair of bypass orifice first network and the second networking equipment, make the second networking equipment can carry out message interaction by this interface and first network.
For routing device or non-routing device, also all can proprietary protocol between use equipment, make when the first networking equipment is normal, can not message transmission between the first interface of the first networking equipment and the second interface, used proprietary protocol is no longer described in detail at this.
